As we approach the 70th anniversary of the liberation of Jews from Nazi concentration camps, efforts are being made to record the stories of the few remaining survivors.

Filming has begun, to preserve the memories of those who left places like Auschwitz alive, using specialist technology, to allow them to interact with people, long after they have gone.

In the latest of special reports cameras have been allowed into the studio where the first of a series of interviews is being recorded in three dimensions, to save the stories of the survivors for future generations.
